Changes in Brain Activity in Tactile Stimulus Therapy and Ruka Ruk Therapy Compared to Mirror Therapy in Upper Limb Rehabilitation.

This is an experiment measuring EEG to healthy adult probands during mirror therapy and VR mirroring therapy in the upper limb. The experiment will be supplemented by haptic contact and stimulation of the upper limb with a foam roller. According to the instructions, the participants will perform a predetermined movement with one upper limb - clenching the fist. In one part with the mirror, in the other part the sensor for sensing the movement of the hand detects the movement, the software creates the illusion that the patient performs the same movement with the dominant and non-dominant upper limb. The patient sees on the screen the illusion of movement of both of his upper limbs. During therapy, the other upper limb will be tactively stimulated haptically and with a foam roller. Data collection will take place by measuring the electrical activity of the brain using an EEG device. The obtained data will then be processed and evaluated with the help of the sLORETA program. The aim of this work is to compare the brain activity from the above therapies with the resting state of the proband and to focus on the activity of mirror neurons.
